The Dodgers spent another $20,000 on a waiver claim Thursday, this time to acquire left-hander Eury De La Rosa from the Oakland Athletics.
De La Rosa, 25, will be assigned to triple-A Oklahoma City.
De La Rosa’s major-league experience is limited to 44 relief appearances he made for the Arizona Diamondbacks from 2013-14. He was 2-1 with a 4.21 earned-run average.
To clear a place for De La Rosa on the 40-man roster, the Dodgers transferred pitcher Brandon McCarthy to the 60-day disabled list.
McCarthy, who was signed to a four-year, $48-million contract in the off-season, was scheduled to undergo reconstructive elbow surgery on Thursday morning.
